This invention relates to rubber strips for use in forming tight joints in windows and doors and other places, more particularly for the sliding windows ot motor vehicles.

Generally stated, therefore, the object of the invention is to provide a rubber stri in the nature of a weather strip, that will orm a tight joint between the window frame and theedge of the glass, so that when the sliding window is closed a tight joint will be formed,

increase the general efliciency and desirabilityof a rubber weather strip of this particular character.

To these and other useful ends, the invention consists in matters hereinafter set' forth and claimed and shown in the accompanying drawingsin which? Fig. l is a side, levation of the upper bbdy portion. of a motor vehicle, showinga sliding.

window having rubber stripping at the edges thereof, involvingthe principles of the invention.

, formed,

Fi 2 is an enlarged detailed section on line 2-2 in ri i.

base portion 5 of the rubber strip is also preferably provided with a longitudinad opening t, to make the strip more yielding and resilit. Between the two flanges 1 a longitudinal rib 7 is provided as shown. Preferably, this rib is oblique, and is adapted at its edge to engage the edge of the glass 2, when the latter slides upward to close the window.

The rib 7 will yield 'sulficiently to insure a tight joint between the edge of the glass and the rubber strip, throughout the entire length of the ed e of the glass, very obviously, notwithstan ing that the rubber strip may not be perfectly straight.

The dificulty with the ordinary rubber strips, for this purpose, is tllatin'any times when they are fastened in place they are not straight, so that the surface to be engaged by the edge of'the glass is wavy or uneven, with the result that when the glass slides upward its upper edge will strike certain portions ofthe rubber strip, while otherportions of the edge ofthe glass will not be engaged by the rubber, thus preventing formation of a tight joint betweenthe strip and the glass for v the entire length of the edge of the-glass.

-However,w ith the provision of yielding means between the edge of the glass and the bottom of the channel in the'rubber strip, it is obvious that any unevenness in the length of the strip will not prevent the formation of atight joint between the rubber and-the glass, for the full length of the edge of the glass, inasmuch as the rib 7 will yield readily until all portions of the edge of the glass are firmly engaged by the rubber strip; Without the rib 7, the rubber strip shown and described will be liable in some cases to fail to form a continuous tight joint between the edge of the glass and the rubber, as it would require considerable compression of different portions of the base of the strip, in cases where the underside of the strip was uneven, in order toforce the glass up'against the other portions of the rubber, and in order to thus uniformly flatten the entire length of the rubber. surface against which the upper edge of the glass would be forced into engagement. However, with the provision of the rib 7 or with the provision of more readily yielding means between the edge of the glass and the base of the channelshaped rubber strip, the wavy or uneven condition of the underside of the strip will not prevent the formation of a tight joint throughoutthe entire length of the edge of the glass.

Of course, it -is obvious that -a rubber strip of this kind can be used for different purposes and in different places, and the invention is not limited to the particular use shown in the drawings. The strip is preferably made of rubber, but it can be made of any other resili ent or yielding material which will form a tight joint and in the claims the word rubber will be understood to mean any resilient or yielding material suitable for' this purose. P While the invention is shown and described in connection with a channel strip, it will be understood that the improvement can be used on a strip of any suitable or desired sha e, for

the invention is not limited to the speci c con- 'struction shown and described. With the provision of the tongue or rib 7, a tight joint 'is'insured, as explained, regardless of irregularity in the frame, thereby making a continuous and tight contact with the edge of the glass, even through the body portion of the strip might not be perfectly straight, or

might be irregular at different points in its length.

Without disclaming anything, and without a longitudinal opening between said grooves.-

prejudice to any novelty disclosed, what we clalm as our inventionis: I

1. A rubber strip for use in forming a tight joint in any desired structure, comprising a rubber channel having an integral base ortion and flexible side walls having an anc oring portion by which the strip is fastened in 7 place on the structure, and having a flexible" web disposed obliquely in the channel and integral with the base portion of the stripand adapted to engage the edge of some. element of said structure, when the edge portion of said element is moved in the channel strip,

said oblique web being flexed toward one side wall and toward the base, by said element, providing a tight joint between the strip and the ed e of said element for the full length of said e ge.

2. A structure as specified in claim 1, said web having its base portion adjacent to one side wall, and having' its free edge adjacent the other side wall.

3. A structure as specifiedin claim 1, said element being a sliding window, whereby said rubber strip serves as a weather strip to make the window tight when closed, said web be ing subject to lateral fiexure and distortion by the edge of the window to form a uniform tight joint. 7
